Novel material large-diameter annealing machine

Abstract

The invention discloses a large-diameter annealing machine for novel materials, which comprises a pre-annealing wheel, a guide wheel 1, a guide wheel 2, a guide wheel 3, an upper annealing wheel, a lower annealing wheel, a constant speed wheel and a wire rod leading out Guide wheel four, wherein, the pre-annealing wheel to the upper annealing wheel is the preheating section, the annealing section is between the upper annealing wheel and the lower annealing wheel, and the cooling section is between the lower annealing wheel and the guide wheel four. It is as follows: the cooling tank in the cooling section is placed horizontally, and the cooling liquid circulation system in the cooling section is provided with a plate heat exchanger, and the number of carbon brushes on the carbon brush wheel used in the large-diameter annealing machine is eight Group. An air cooling system is arranged on the carbon brush wheel. The length of the preheating section is 9800-10000 mm. The length of the cooling section is 2225-2435 mm. The diameters of the upper annealing wheel and the lower annealing wheel are φ440˜φ460 mm.

Description

technical field [0001] The invention relates to an annealing machine, in particular to a large-diameter annealing machine for new materials. Background technique [0002] The diameter of the annealing wheel of the existing bare copper wire online annealing machine is φ400mm, the annealing cooling tank is installed obliquely, and there are only three sets of carbon brushes on the carbon brush wheel. This structure has the following disadvantages in use: 1. It is on the top of the inclined section 2. Due to the lack of carbon brushes on the carbon brush wheel, the annealing current is too small to achieve online annealing for bare copper wires with a large diameter of φ3.5mm~φ4.0mm, and the carbon brush wheel is working At the same time, there will be heat transfer between the wire rod and the annealing wheel, and at the same time, heat transfer between the annealing wheel and the carbon brush wheel will cause the carbon brush wheel to heat up and the temperature will rise, an...

[0002] The diameter of the annealing wheel of the existing bare copper wire online annealing machine is φ400mm, the annealing cooling tank is installed obliquely, and there are only three sets of carbon brushes on the carbon brush wheel. This structure has the following disadvantages in use: 1. It is on the top of the inclined section 2. Due to the lack of carbon brushes on the carbon brush wheel, the annealing current is too small to achieve online annealing for bare copper wires with a large diameter of φ3.5mm~φ4.0mm, and the carbon brush wheel is working At the same time, there will be heat transfer between the wire rod and the annealing wheel, and at the same time, heat transfer between the annealing wheel and the carbon brush wheel will cause the carbon brush wheel to heat up and the temperature will rise, and the heat generated can only be dissipated by natural circulation. The speed is slow, which reduces the insulation level of the insulating parts; 3. There is no heat exchanger in the cooling liquid circulation system, and the temperature of the annealing liquid cannot be lowered in time; 4. Due to the short length of the preheating section and the cooling section, the wire cannot be fully , uniform heating and cooling

[0003] In addition, the guide wheels and annealing wheels used in the annealing machine in the prior art are all made of metal, but the surface is not coated with paint, resulting in greatly reduced high temperature resistance and friction resistance, resulting in a greatly reduced service life.
